Statistical Thermodynamics of Biological Systems

How do proteins fold? Why do molecules bind? Statistical thermodynamics provides the essential framework for understanding the forces and energies that drive all biological functions at the molecular level. This course provides a foundational understanding of statistical mechanics applied specifically to biomolecules. You will move beyond classical thermodynamics to analyze molecular ensembles, predict equilibrium states, and quantitatively model complex phenomena like binding cooperativity and solvation effects that are critical in biochemistry and modern drug design. What you'll learn: * Understand the fundamental concepts of statistical mechanics, including ensembles, partition functions, and entropy, as applied to biological systems. * Apply principles of chemical potential and free energy to predict equilibrium states and analyze molecular stability. * Analyze the thermodynamics of macromolecular behavior, including protein folding, ligand binding kinetics, and cooperative interactions. * Model the physical chemistry of biomolecules in solution, focusing on solvation effects and behavior at interfaces. * Practice conceptualizing basic computational methods, like molecular simulation concepts, used to study complex molecular dynamics. The course begins with defining key terminology and foundational concepts in classical and statistical thermodynamics. It then progresses through applying these principles to specific biological problems, such as analyzing binding curves, understanding macromolecular conformation, and exploring solvation dynamics. This course is designed for absolute beginners interested in biophysics, biochemistry, or biological engineering. No prior advanced knowledge of statistical mechanics is required—only a basic understanding of chemistry and calculus is needed.
